DBD plasma treatment and chitosan layers - A green method for stabilization of ...

The addition of silver nanoparticles (AgNPs) to biomedical textiles can be of great interest to protect the materials against microorganisms and prevent their spread. However, the human and environmental over‐exposure to AgNPs is leading to numerous concerns due to their toxicity. In this work, AgNPs were stabilized onto polyamide 6.6 fabrics (PA66) through atmospheric dielectric barrier discharge (DBD) plasma ...

Antimicrobial efficacy of low concentration PVP-silver nanoparticles deposited ...

In this study, a low concentration (10 μg·mL−1) of poly(N-vinylpyrrolidone) (PVP)-coated silver nanoparticles (AgNPs) were deposited by spray and exhaustion (30, 70 and 100 ◦C) methods onto untreated and dielectric barrier discharge (DBD) plasma-treated polyamide 6,6 (PA66) fabric. DBD plasma-treated samples showed higher AgNP deposition than untreated ones for all methods. After five washing cycles, only DBD p...

Atmospheric-pressure plasma spray deposition of silver/HMDSO nanocomposite on p...

Efficient silver nanoparticles deposition method on DBD plasma-treated polyamid...

Several methods for silver nanoparticles (AgNPs) deposition on dielectric barrier discharge (DBD) plasma treated and not treated polyamide 6,6 fabric were tested for the production of durable antibacterial textiles. Ultrasound-assisted, dip-coating, exhaustion at 70 ̊C and spray deposition methods were applied. The treated fabrics were analysed in terms of coating uniformity, plasma effect, nanoparticles concen...

Atmospheric pressure plasma and depositions of antibacterial coatings

Healthcare-associated infections (HCAI) are complications of healthcare that result in elevated patient morbidity and mortality. HCAI present a huge financial burden for patients, hospitals and insurers due to extended hospitalisation and associated care. According to the estimations, in the US alone, HCAI affects approximately 2 million patients annually, of whom approximately 90.000 patients die, with an esti...

Efficient silver nanoparticles deposition method on DBD plasma-treated polyamid...

The study of antimicrobial fabrics with silver nanoparticles (AgNPs) incorporation has shown excellent properties in medical, pharmaceutical, cosmetics and electronics applications due to their formidable action against pathogens, preventing and treating infections.[1] The high surface-to-volume ratio from AgNPs promotes an easy release of silver ion, responsible for the antimicrobial effect.[2] The most tradit...

Antibacterial nanocomposites based on Ag NPs and HMDSO deposited by atmospheric...

The development of new multifunctional coatings with antimicrobial properties has a special interest in several applications for pharmaceutical and medical products. This work reports on the deposition of antimicrobial coatings based on silver nanoparticles (Ag NPs) embedded in an organosilicon film onto woven and nonwoven textiles. The Ag nanoparticles admixed with hexamethyldisiloxane (HMDSO) vapours are intr...

Antibacterial composite coatings of metal nano-particles on textiles and plasti...

Non-woven textile materials with antimicrobial properties are of high demands for applications ranging from medical dressing to everyday cleaning products. We proposed plasma assisted route to engineer polymer films and non-woven fabrics with antimicrobial nano-composite coatings. Atmospheric pressure plasma is used for deposition of nano-composites. Nano-particles Ag, Cu and ZnO are tested as antimicrobial age...
